I couldn't understand this passage, taking two hours. Please show the right reading. I am a beginner in reading Greek, but usually I can read this book without getting stucked.

homale^s = adj. even, level, equal, alike, homogenious
pho^s = n. light
ae^r = n. air
poros = n. passage (the air has passage ways that let the light pass though it)
entha = adv. there / where / when
pepho^tistal = pho^tizo^ (shine, emit light)
diaphane^s = adj. transparent
